The Fuel that helped us get 5th at Adventure Race World Championships, and so much more!
Cold weather changes everything — your metabolism, your hunger cues, your energy — and yet somehow, as moms, we’re still juggling homeschool, work, scheduling, holiday events, and trying to squeeze training in before the sun sets at 4:42 p.m.
And listen… none of us athlete+ Moms have time to craft gourmet winter fueling strategies. But I have good news: winter fueling doesn’t have to be complicated. It can be simple, warm, grounding, and incredibly effective.
Honestly, the hardest part is just trusting the process.
Lately, I’ve found that the less I overthink, the better I follow through. When my fueling plan is distilled and clear, my energy is steadier, my workouts feel better, and I’m far less likely to hit that 3 p.m. crash that makes me want to live inside the snack drawer with my kids.
So I wanted to share what’s been helping me this winter — the things that actually matter when it comes to fueling cold-weather training.
Here are my go-tos:
Have your own? I'd love to hear them! Post a comment or email me!
Your body uses extra fuel to stay warm, manage shivering, increase tension, and balance temperature swings. So if winter training feels sluggish, there’s a 90% chance the issue isn’t fitness—it’s under-fueling.
A common scenario:
You ate a big breakfast, worked for a few hours, then headed out the door with just water and one 90-calorie gummy packet for a “just in case" moment.
A better option:
This one shift can completely change your winter energy.
Your metabolic rate ramps up faster in cold weather. That means eating a breakfast that has 25-30 grams of protein in it is crucial. Even better for your all around health would be to drink a big glass of water first thing in the am, followed by breakfast AND then coffee (if you drink it that is!). I always find that if I start my day like this, I am already starting it with a feeling of success and am better at resisting the temptation to dip into the snack drawer alongside my kiddos through out the day.
A few easy wins include:
An added bonus of all of these is that my kids love all of these options and their little furnace bodies definitely need winter calories as well. Cold mornings require warm nourishment. Don’t make your body beg for it.
Adding extra calories to your longer training sessions is not "treating yourself", it's necessary and good for you to start thinking of it as "fuel" to keep you feeling strong and powerful while you are out doing your thing. If you come home starving, you will most likely do what we all do: raid the fridge with out thinking about what your body really needs and instead over eat on empty calories. Trust me, I have done this plenty of times, and it never feels good afterwards.
What is a good option you ask? Below are my favorites for in training fueling.
Winter is no time for the “I’ll just push through” attitude. It's a time to rebuild and train yourself to keep eating while you train.
Cold blunts thirst cues by up to 40%.
That means you’re under-drinking even when you think you’re fine.
3 of my go to strategies:
Hydration is the quiet variable that keeps your winter energy stable and your immune system supported.
If you finish cold, your body is in a stress state. Post-training food calms the system, replenishes energy, and speeds recovery. Prep something before you leave so it’s effortless when you return.
Cozy recovery ideas:
Your winter recovery meals should feel like a hug. Something warm, nourishing, and deeply satisfying.
You’re not just training. You’re lifting kids, carrying gear, homeschooling, working, driving, managing schedules, and squeezing in movement whenever life cracks open a window.
Winter is heavier, stress is higher and days are shorter.
Under-fueling is one of the biggest performance and mood limiters for active moms during the cold season.
Remember:
More fuel = more energy = more consistency = a happier, stronger Mama.
Winter can feel long, dark, and demanding, but it can also be a season of rebuilding, softening, and quietly getting stronger. Fueling well is one of the kindest things you can do for your body right now. So give yourself permission to eat enough, to drink enough, to warm yourself up, and to honor the work you’re doing- both inside and outside your workouts.
Spring miles are built in winter kitchens. And, you deserve to feel strong ALL season long.
We debated long and hard about keeping this secret for ourselves as athletes, but the only thing that is more rewarding than being on the podium at an ultra-distance event, is helping others get to their personal podium! Over the past three years, we've had such success with this formula and fueling paradigm. It has been an integral part of the team's success at our wins of the Patagonian Expedition Race, Expedition Canada, Everglades Challenge, WA360 paddle race, and Chesley's Solo 24 national title. The longer the race (or stage), and the higher output we want/need to maintain - the more crucial it has become.
Energy uptake is key for a great performance in sport over 3 hours. After 15 years with long distance endurance sport I have gotten tired of food during races. But energy that you can drink is easy to consume and get you going.
I always divide my food in 3 groups: high density energy, motivational stuff and funfood. This 4-hour Fuel counts as all 3 at the same time.
24-hour races are all about efficiency if you want to be competitive. In the 2021 USARA nationals, we used 4-hour fuel as 90% of our calories. We never got sick of it and felt powerful on every stage. My team's race plan now includes 4-hour Fuel!
My name is Mateo and I am an ultra endurance bike pack racer based in Bend, Oregon. I have been using your product now for a few months and cannot praise it enough. With the rigors of training, travel and racing, your product is honestly the best supplemental calories in a mixable form that I have ever found.
Daniel Staudigel
fuel designer
Team Bend Racing's Daniel Staudigel developed the initial iteration of 4-Hour Fuel after after his spectacular bonk was filmed for all to see in Amazon's "World's Toughest Race: Eco Challenge Fiji". He needed a more efficient and easy tasting fueling solution for his expedition racing. Since that inception, Team Bend Racing has used the 4-hour fuel across the globe on their way to podium placements in expedition races, 24 hour solo mountain bike events, FKTs, and ultra distance paddling races. Now it is your turn to try it.
How to mix:
Front Country Option (at home) - fill your bottle of choice 2/3 with water (we use a standard 16 or 20 oz bike bottle). Pour that water into a blender, toss in the entire powder packet and blend. Dump into your bottle, and top it off with water. Shake. Go get after it.
For long races that are not super hot, we pre-mix most bottles this way, and leave them in TA bins for up to 60ish hours and have had no problems.
Backcountry mixing (In the TA) - Fill bottle half full with water, then add half the powder and shake like crazy. Add a bit more water and the rest of the powder and shake again. Top off with water and shake as you leave the TA on the way to greatness.
Mixing notes:
It is fine to mix the 4-hr fuel at less than full strength (we recommend at least 1/2 the pack, and then - Congrats, you just made 2-hour tea!), but if you are mixing just 1/4 serving in a bottle (200 cal) - well there are heaps of products out there that do that same thing and will likely taste better at that dilution. We've mixed this formula at all strengths from 2-6 hours in a single bottle and consensus is that the 4-hour strength is the best taste/nutrition/weight ratio for us. Remember, this is high density caloric fuel! That bottle is supposed to last you for 4 HOURS. So it is not your primary hydration source. Carry a separate bottle or bladder with good old straight water. Yum.
Product Concept - we are firm believers in simplicity and science, and yet our experience in expedition racing has often put us into physical and emotional places that are very under-researched. There is plenty out there on how to fuel for a marathon, or a Ironman....but what about when you have to carry all your food?!? No aid stations. Unfathomable distance. And then we add sleep deprivation which just makes everything (fueling included) so much harder.
For our team - this product solves many problems. It eliminates choice. Having a singular primary and palatable fuel source takes the "choice" aspect away from where we get our calories. We know we are getting a "race proven" mix of easy to digest complex carbs, plant based protein, extra BCAAs, electrolytes, and natural fruit sugars.Liquid food is much easier to digest in many race situations, allowing for endurance racers to maintain a competitive output. Bike bottles are convenient and fast to drink from, making it easy to stay fueled on the legs (bike and paddle) that generally have athletes having to choose between slowing down to eat or digging a deep caloric hole as they try to maintain speed and efficiency.
Have questions? Of course you do. Fire away. You can email us at bendracingor@gmail.com or reach out to Jason Magness or Daniel Staudigel or Bend Racing on FB and we are happy to talk. If you wanna tag us in your adventures - we might as well start using #4hourfuel. Thanks so so much everyone.
